Kata the amazing Harry Potter witch.
I'm Finnish, and even though I write and read English every day I never actually speak it so my spoken English is very clumsy and I have no idea how to pronounce words. Even if I knew how to pronounce something, if it was a bit more difficult a word it would most likely still come out all wrong. So, one night I was wondering how I'd be absolutely doomed if I ever were to meet dementors as I can barely say "expecto patronum" on a good day, let alone when I'm surrounded by creatures like that.
